didnt know there was iron in it.. thanks.. but iron chloride, shouldnt that be possible to remove that by letting it dry out, where it would go into
Fe2O3 and Cl2 at some point?

1.05 SG would put the concentration at about 11 %. That's not very consistent with the observed fuming, though.
11 % HCl is about 3.2 M (mol/L). 69 g of K2CO3 is 0.5 mol and needs 1 mol of pure HCl, so about 312 ml of 3.2 M HCl.
As your product dries the FeCl3 will hydrolyse to Fe(OH)3 (the Cl elutes as HCl), which on drying becomes Fe2O3. |
